Ученые поняли, почему боксеры страдают ранней деменцией

Не секрет, что многие профессиональные спортсмены, в частности, боксеры или игроки в американский футбол, часто страдают так называемой хронической травматической энцефалопатией. Это такая болезнь, которая вызывается так называемым тау-белком, но при этом структурно не похожа на болезнь Альцгеймера, которую, кстати, вызывает тот же белок.

Травматическую энцефалопатию также называли «Деменцией боксеров». Считается, что она вызвана частыми травмами головы. Ее основными признаками считается отложения тау-белка в нейронах, и вокруг кровеносных сосудов в головном мозге – он приводит к смерти его клеток.

Специалисты из Кембриджа проанализировали мозг боксеров, которые страдают этой болезнью и пришли к выводу, что на нее влияет в первую очередь структура нитей тау-белка, а не какие-то другие факторы. Поэтому болезнь развивается не у всех пациентов в группе риска, а только у тех, кто имеет к этой болезни определенную расположенность.

Работа ученых позволит найти способы лечения болезни, ведь она практически не диагностируется. Сейчас диагноз ставят только после смерти пациентов.
